In Ovid's Fasti the author mentions the ancient idea that Saturn (identified with Cronus), after Jupiter (identified with Zeus) had dethroned him from the celestial realms in Olympus, had wondered through the seas on a ship until he came to the Tuscan river. Hence the peopled were called Saturnian and the land Latium (from latente).[3]
From this it may be that the gulf became known as the Sea of Cronus.
